RFC 20 – ASCII Character Chart

ASCII Code Chart

ASCII format for Network Interchange
For concreteness, we suggest the use of standard 7-bit ASCII embedded in an 8 bit byte whose high order bit is always 0. This leads to the standard code given on the attached page, copies from USAS X3, 4-1968. This code will be used over HOST-HOST primary connections. Break characters will be defined by the receiving remote host, e.g. SRI uses “.” (ASCII X’2E’ or 2/14) as the end-of-line character, where as UCLA uses X’OD’ or 0/13 (carriage return).
USA Standard Code for Information Interchange
